VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent Nol 505,508, dated September 26, 1893.

Application filed April 26, 1892.A Serial No. l30,659. (No model.) Y

To all whom it may concern:

Be it known that I, JOHN A. CHANDLER, of Kansas City, .Iackson county, Missouri, have invented certain new and useful Improvementsin Vapor-Burners, of which the followa complete vaporization of the liquid fuel and a complete combustion of thevapors so produced; furthermore, to producea vapor-.` burner which, in addition tothe advantages` above enumerated, shall be under perfect and easy control of an attendant or operator.

To the 'aboveA purposes'my invention con, sists in certain peculiar and novel features of construction and arrangement, as hereinafterl described and claimed.

burner embodying my invention. Fig. 2 is a plan View of the same. Fig. 3 is a horizontal section of the same, on the line 3 3 of Fig. 1. Fig. 4 is a transverse vertical section of the same, on the line YIM-eiE of Fig. l. is a detached invertedplan view of a modified Fig. 6 is a detached perspective view of the `removable foraminouslighting-plug of the burner.

In the said drawings l designates the base of` my improved burner, the said burner being a metal casting of circular form and of any suitable or preferred dimensions. At the under side of this base is formed, or suitably secured, a cross bar 2, which extends diametrically across the base l and the center or -middle of which is formed with an enlargement orV boss 3, through which extendsthe lower externally screw-threaded end of a vertical fcoupling-bolt 4, the purpose of which will be hereinafter explained. From. the outer margin of the base l extend outwardly four or any other suitable or preferred number of radial lugs or ears 5 which are preferably cast integrally with the said base, and Which'serve to support the outer non-foraminous casing Gof the burner. The upper'side of the base l is formed with two vertical concentric walls 7 which are preferably formed integrally with the base 1, and which inclosea circular space the bottom 8 of which is preferably concave in form, and the top of which is open. Thus theV base l is practically U-` shaped in cross-section for a purpose to be hereinafter explained.

9 and 10 designate two cylindrical foraminous and vertical walls, which are preferably of perforated sheet metal, but which may also be of any other suitable non-combustible foraminous material; the openings or perforations of said walls being at a slight `disy tance above the lower margins of the walls andcontinuing tothe upper margins of the same, as shown. The lower margin ofthe `outer foraminous wall 9 surrounds the outer l Wall 7 of the base 1 and abuts closely against InV order that my invention may be fullyl understood, I will proceed to describe it with` reference to the accompanying drawings, in

the outer side of said Wall 7, While the lowe margin of the inner wall lO is surrounded by the inner wall 7 of the base l and abuts g closely against the inner side of vsaid Wall 7. Figure l is a side elevation of a vapor- These foraminous Walls 9 and lOare of equal height and of about the proportionate height, relative tothe base-walls 7, as shown. lThe outer `wall'or casing 6 of the burner is of sheetmetal,or other suitable non-combustible material, and is also non-foraminous in its character; said outer casing corresponding IOO lateral displacement ot' the lower end of the" outer casing 6, the lugs or ears 5 may be formed upon their uppersides with lugs, or equivalent projection 11, which abut against the outer side of the lower margin of the casing 6, and thus prevent lateral displacement of this part of the casing.

The top of the burner is formed by a horizontal cap-plate 12 which corresponds in diameter with the diameter of the inner vertical foraminous Wall l0, and through the center of which extends the upper end of the coupling-bolt 4;*the head 14 of said bolt resting upon the upper Side of the said cap. At the under side of its circular margin, the capplate 12 is formed with a circular groove 15 into which enters the upper margin of the inner wall of the burner, the said groove preventing lateral displacement of the inner lforaminous wall l10. The top-plate 12 is surrounded concentrically by a ring 16 which is connected, preferably integrally with the topplate, by a number of radial arms 17 which project horizontally outward from the capplate 12. The circular space between the outer margin of the cap-plate 12 and the inner margin ofthe ring 16 is equal in width to the width of the space which intervenes ,between the foraminous walls 9 and 10; the

cular marginal grooves 18 and 19 the groove 18 being at the inner and the groove I9 at the outer margin of the ring. The upper margin of the outer foraminous wall 9 enters the inner groove 18, and the upper margin ot' the outer casing 6 entering the outer groove 19 of the ring 16. The coupling-bolt 4 passes vertically downward through the center of the plate 12 and also through the enlargement or boss 3 of the cross-bar 2,as before stated, and upon the lower end of this bolt is secured a nut 20 which retains the parts in position. It will thus be seen that the downward strain upon the bolt 4, produced by the nut 20, prevents all possibility of lateral displacement of the foraminous walls 9 and 10 and also of the outer non-foraminous casing 6.

In Fig. 5 I have shown a modified construction of the top or cap plate 12; the said plate being, in this instance shown as of foraminous material, or in other words, as provided with numerous openings or holes, instead of being entirely closed, as before. In form and operation, the plate 12 is alike in both cases.

21 designates the feed-pipe of the burner; said pipe being designed for connection at its outer end with a suitable tank or reservoir for gasoline, or other liquid fuel. This pipe passes inward through the lower part of the casing 6, and also through the adjacent part of the outer foraminous wall 9. The inner portion 22 of this feed-pipe is bent into circular form, as shown, and is provided with a number of perforations 23 which are formed, preferably, through the under side of the pipe as shown, but which may be formed completely or otherwise partially around the circumfcrence of the pipe. The circular inner portion 22 of this feed-pipe extends horizontally within the lower part of the space inclosed by the foraminous walls 9 and 10 of the burner, and a slight distance above the vertical base-walls 7. The inner end of this feed pipe is closed. This is done in order to check the flow of the oil, it the discharge from the reservoir should at any time be greater than the capacity ot" the perforations in the feed pipe to discharge it into the U-shaped cavity, and thus prevent uneven distribution of the oil into the said cavity.

24 designates the lighting-tube of the burner, said tube extending horizontally through au opening in the lower part ot the casing 6, and also through a similar opening in the lower part of the outer foralninous wall 9 of the burner. Within this lighting-tube 24 is mounted a removable plug which consists of a hollow cylindrical body-portion 25l at each end of which is a foraminous disk 26. Through the body-portion 25 extends a stem 27, the outer endof which is preferably formed with a suitable hook 28, or an eye, or an equivalent attachment.

From the above description, it will be seen that when the burner is to be used, a quantity of oil is first allowed to flow through the feed-pipe, and run through the openings 23 into the cavity inclosed by the side-walls7 of the base 1. The lighting-plug is now removed from the burner and a flame from a match, or from any other suitable source, is introduced into the lighting-opening, so as to ignite the oil in the cavity, and heat the inner part 22 of the feed-pipe; thus starting vaporization. As soon as vaporization has been fully started the lighting-plug is replaced, and owing to the foraminous character of the disk 26, sufficient air is admitted through the plug to support combustion. Owing to the positionof the feed-openings 23, the ,fiames heat the base 1 and its walls 7, and thus assist in the vaporizing action, and sufficient air to support combustion flows inward through the openings of the foraminous walls 9 and lO, so that the space between said walls is filled with flame. Air to support combustion flows upward through the middle of the base 1 and also through the space intervening between the outer margin of the base 1 and the lower margin of the casing 6; such air thence flowing through the openings of the foraminous walls 9 and 10, as just stated. The outer casing 6 prevents ineffective outward lateral dissemination of the heat, while the cap 12 also prevents inward lateral dissemination of such heat; the heat being thus projected in concentrated manner at the top of the space inclosed between the foraminous walls 9 and 10 of the burner. v

From the above description it will bev seen that I have produced a vapor-burner which is simple, strong, durable, and inexpensive in IOO construction, automatic, reliable, and economical in its action, and which is completely under the control of an attendant.

It is to be understood,that while I have shown and described the burner as of general circular form, it may be oval, elliptical, square, or polyangular, without departing from the essential spirit of my invention.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
